We had a security light installed for my mother at her back door which
worked fine for a couple months. Now when someone walks up to the door it
no longer comes on but when you walk back to your car then it comes on.
How
do we fix this? TIA


Zillions of things cause this. Shall we pick a few.
Read the direction to see if there is a sensor adjustment.
COLD on el cheap o stuff
Aiming of the sensor
